Some say it's healthy. Fapping is a sign of a healthy sexuality. That we should unclog the pipes from time to time because it is not good for the body. It is also a form of stress reliever (for that I agree). But the additional question is, how many times should we do it? The answer is "Who cares? It is your own body. Do what you want with it." And most of the people here will agree.
While others say it's not healthy. The penis doesn't need unclogging. It won't hurt you if you don't fap. But the pleasure it gives when playing and releasing is uncanny.
The question above is still unfathomable. An enigma for every person. It will continue as a subject for debate but it won't stop me from giving pleasure to myself.. haha
